CARBURETER.

SPECIFICATION forming part of Letters Patent No. 230,656, dated August 3, 1880. Application filed April 10, 1880. (No model.)

To all whom tt may concern:

Be it known that I, BERNARD RADKEY, a citizen of, the United States, residing at Austin, in the county of Travis and State of Texas, have invented certain new and useful Improvementsin Garbureters 5 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to that class of car- .bureters in which a float is used to keep the fibrous material at the proper position in the gasoline; and it consists in the construction and arrangement of parts, hereinafter more fully described.

Figure 1 represents a vertical section of a carbureter constructed according to my improvement; Fig. 2, a horizontal section of the float; Fig. 3, a bottom view of the same; and

Fig. 4, a detail, showing the method of holding the fiber.

A represents the gasoline-chamber, provided with a dome, B, having a screw-cap, G, from which rises the pipe D, having at one side the air-supply pipe E. From the top of the chamber A rises another tube, F, closed by a screwcap, and having at its side the outlet-pipe G.

H represents an annular chamber forminga float. Inside of the inner walls of this floatchamber is a series of concentric cylinders, a a a, each of which is fastened by air-tightjoints to the top I) of the float H, and are kept at a suitable distance apart by the cross-bars c 0, arranged near the bottom and top of the cylinders, and extending between them, the crossbars breaking joints with each other.

The annular spaces formed between the cylinders a a are interrupted by division-plates d (1. Each cylinder has a hole, 0, through its side near the division-plates, and the top plate,

I), has a hole at f. Between each pair of the cylinders there is a quantity of cotton wicking, w, or any other suitable material, which is passed under and over the cross-bars c c c, as shown at Fig. 4.

Rising from the center of the float is a tube, 1, which may or may not form an extension of the inner cylinder at, and which passes into the dome B, and is packed to make an airtightjoint by winding wicking around it and then pressing the wicking down by means of a ring, J, which ring is held down by sprii'lgrods jj, the ends of which engage with the teeth of racks k on each side of the dome.

The chamber A should be sunk into the ground at a suitable distance from the house, to prevent danger from fire, leaving only the small screw-caps above ground, and the pipes E and G connected, respectively, to an airforcing apparatus and the system of pipes supplying the burners in the house.

To supply the chamber A with gasoline the small screw-caps should be removed and gasoline poured through the supply-pipeD into the chamber, from which the air will pass out through the air-tube F. The gasoline should be poured in until the float is carried up so high that the top of the tube I will touch the screw-cap 0 upon the dome, which will readily be seen by the rising through the pipe D of a pin, 'i, on the top of the pipe I, which pin should be attached to one side of tube I, so as not to interfere with the pouring of the fluid. When the chamber has been supplied with gasoline air is forced in through the pipe E, and it passes down through the tube I and through the hole 6 in its side to the wicking, and passing between the cylinders at ac and apertures c in their sides in'opposite directions alternately, as shown by the arrows, will finally pass through the hole f into the space above the float, from whence it passes through the outlet-pipe G to the burners, having become thoroughly saturated with gasoline-vapors in its passage through the wicking. As the gasoline is absorbed by the air the float Hdescends, so that the wicking is always kept in a saturated condition, and the air, being compelled to take a circuitous course in opposite directions through the wicking, will always take up the gasoline in its passage through the machine. y

By this construction a carburetor can be made that is cheaply manufactured, readily attended to, and one not apt to get out of order.

The arrangement and construction of the float are such that the wicking is always kept thoroughly saturated.

The arrangement for packing is also very (No Model.)

GEORGE RAMSDELL, OF OSWEGO, NEW YORK.

APPARATUS FOR THE MANUFACTURE OF WOOD AND OIL GAS.

SPECIFICATION forming part of Letters Patent No. 230,657, dated August 3, 1890.

Application filed May 1, 1880.

To all whom it may concern:

Be it known that I, GEORGE RAMSDELL, of Oswego, in the county of Oswego and State of New York, have invented certain new and useful Improvements in Apparatus for the Manufacture of Wood and Oil Gas; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanyingdrawin gs, which form part of this specification.

My invention relates to an improved apparatus for the manufacture of wood and oil gas; and the invention consists in certain details of construction and combinations of parts, as will hereinafter be described, and pointed out in the claims. 7

In the accompanying drawings, Figure l is a view, in perspective, of a bench of retorts embodying my invention. Fig. 2 is a view in front elevation. Fig. 3 is a longitudinal section of the superheating-retort. Fig. 4 is a longitudinal vertical section through theoilretort and cylinder surrounding the feed-pipe. Fig. 5 is avertical section of the valve-casing and pipes connected therewith. Fig. 6 is a longitudinal section of the hydraulic main.

A A represent wood-retorts, which communicate with each other by the short connecting-pipe a. B is an oil-retort, which is connected by pipe I) with the wood-retort B. O is a superheating-retort, which is placed above the wood and oil retorts A B. k

A three-way valve, D, is located at the intersection of the three pipes E. E, and F, the latter being connected with the lower compart1nent,c, of the superheating-retort, and depending a short distance therefrom and cornmunicating with the valve-casing D. Pipes E E connect at their upper ends with the under side of valve-casing D, and extend downward and outward in the form of an inverted V, their lower ends being furnished with flanges c, which are bolted to the lower portions of the inner and adjacent sides of retorts A B. It is of the greatestimportance th at the pipes E E shall be located as nearly in a vertical position as possible, in order to prevent the accumulation of any carbon deposit therein, as such deposition operates to clog the passages in the pipes,

(No model.)

thereby obstructing the flow of gas, and hence impairing the operation of the apparatus; and also it is practically impossible to remove such carbon deposits in an apparatus of the type in question except by cutting out the pipes, which operation necessitates delay and great expense.

To obviate such objections the pipes are connected at their lower ends with the lower portions of the two adjacent wood and oil retorts, while the upper and converging ends of the pipes communicate with the casing D of the'three-way valve, thereby insuring a sharp inclination to both of said pipes and preventing any accumulation of carbon deposits therein.

The pipes E, E, and F are cast solid with the valve-casin g D, which latter is ofsuflicient size to constitute a gas-mixing chamber. Within the valve-casing D is located a rotary valve, D, which may be adjusted by applying acrank to the squared end (1 of the valve stem or shaft.

The superheating-retort O is subdivided into upper and lower chambers, d e, by the horizontal partitionf, which extends from the forward to the rear end thereof, a passage-way, g, being provided for the flow of gas from the lower to the upper compartment or chamber.

His a stand-pipe coinmunicatin g at its lower end with the forward end of the upper chamber, d, of the superheating-retort. To the upper end of the stand-pipe H is connected a dip-pipe, I, the latter being arranged in an inclined position, as shown, in order to allow of its connection with the stand-pipe in such a manner as to avoid any horizontal surfaces upon which carbon deposits might accumulate. The lower end, g, of the dip-pipe I extends downward intot-he hydraulic main K a sufficient distance only to form an ordinary seal to the end of the dip-pipe.

L L are stand-pipes communicating at their lower ends with the wood and oil retorts A and B, the upper ends of stand-pipes being provided with inclined dip-pipes M. Standpipes L L connect at their lower ends with the lower wood-retorts, A B, and are also provided at their upper ends with inclined dip-pipes M. The four inclined dip-pipes M extend down into the hydraulic main a greater distance than the dip-pipe I, and hence the re-
